idea下载多个插件项目启动不了解决方案
今天下载mybatis plugin插件的时候
有好多个版本的plugin，然后呢，看第二个比较热门，就下载了第二个，然后重启idea发现这个插件貌似得花钱，那算了吧，咱用第一个免费的吧，就又下载了第一个，然后重启idea。然后。。。就炸了。
瞬间感觉心慌慌的，最后还是借助百度解决了。。
首先看上面那个报错信息，一看就很像jar包冲突的报错信息，先放着，我们再看看idea的日志：C:\Users\{username}\.IntelliJIdea2016.1\system\log\idea.log。在这个路径下，打开idea.log。找到刚刚的报错信息：

最后一段看似和idea启动的时候那个报错差不多。应该是jar包冲突了，但是jar包叫什么名字，在什么地方呢，这是个问题，windows的文件搜索很难找。
于是，下载了一个Everything （该工具可以实现秒查电脑上任意位置的任意文件，堪称本地文件搜索神器，下载地址:http://www.voidtools.com/）。随意的搜了下mybatis，然后按时间排个序，看似找到了。
应该是这两个jar冲突了，删掉那个收费的试试。然后重启idea。完美解决~
